Download or read book Some Stress grading Criteria and Methods of Grade Selection for Dimension Lumber written by Robert L. Ethington and published by . This book was released on 1970 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paper demonstrates procedures for selecting machine grades of lumber based on experimental evidence of what can be produced, along with knowledge of required performance in use. It shows as an example that, for 2 by 8 southern pine floor joists, E-grades with a 1/3 edge-knot limitation are nearly ideal if the joists are used on a 24-inch spacing, or with a 1/2 edge-knot limitation if used on a 12-inch spacing. Relations of bending strength, tensile strength, and compressive strength to full-span modulus of elasticity and strength ratio are given. The methods described can be used for any species. (Author).

Download or read book Nondestructive Evaluation of Wood written by Forest Service (U S ) and published by Government Printing Office. This book was released on 2015 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nature's engineering of wood through genetics, wind, and weather creates a wide variability in wood as a material. Consequently, manufacture and users of wood products are frequently frustrated in dealing with the forest resource. Manufacturers sometimes argue that wood is difficult to consistently process into quality products because of the wide range of properties that exist in this raw material. Users of wood products can be equally frustrated with the performance variability found in finished products. Nondestructive evaluation (NDE) technologies have contributed significantly toward eliminating the cause of these frustrations. NDE technologies have been developed and are currently used in lumber and veneer grading programs that result in engineered materials that have consistent well-defined performance characteristics. This brief volume explores some of the processes that are used to manufacture wood, including green wood technology and provides a bit of history to wood production and its uses too.

Book excerpt: The modulus of elasticity (MOE) is a mechanical property of wood that can be measured rapidly and nondestructively. Research to establish relationships between MOE and modulus of rupture of commercial lumber has been conducted for five principal species of wood. Typical results are presented in this paper. The influences of a variety of interacting wood property characteristics are discussed. It is determined that the effective MOE of lumber containing normal defects of the commercial grades can be used effectively as a structural grading criterion.
